How to configure MQTTthing Homebridge Plugin #1816

Hello,

I need help with the JSON code needed to configure the MQTTthing Homebridge plugin for my AMCOR AC.

The MQTTthing plugin is really convenient to control Homebridge devices and I can successfully send commands to my AC with the following topic code:
"topics": {
"setActive": "amcor/ac/cmnd/power",
"setTargetHeaterCoolerState": "amcor/ac/cmnd/mode",
"setCoolingThresholdTemperature": "amcor/ac/cmnd/temp",
"setHeatingThresholdTemperature": "amcor/ac/cmnd/temp",
"setRotationSpeed": {
"topic": "amcor/ac/cmnd/fanspeed",
"apply": "return [ 'min', 'low', 'med', 'high', 'max', 'auto' ][ Math.floor( message / 20 ) ];"
}
},
The problem is that I need to send 2 commands simultaniously to turn it on. I need to send Power = True and Mode = Auto. I can send power and then set it to auto, and it will turn on, but it's not conveninent.

I tried the following topic code but it doesn't work:
"topics": {
                "setActive": {
                    "topic": "amcor/ac/cmnd",
                    "apply": "state.global.HVAC = state.global.HVAC || {}; state.global.HVAC.Power = message; state.global.HVAC.Mode = ‘auto’; return (JSON.stringify(state.global.HVAC));"
                },
                "getActive": "amcor/ac/stat/power",
                "getCurrentHeaterCoolerState": "amcor/ac/stat/mode",
                "setTargetHeaterCoolerState": {
                    "topic": "amcor/ac/cmnd",
                    "apply": "state.global.HVAC = state.global.HVAC || {}; state.global.HVAC.Mode = message; return (JSON.stringify(state.global.HVAC));"
                },
                "getTargetHeaterCoolerState": "amcor/ac/stat/mode",
                "setCoolingThresholdTemperature": {
                    "topic": "amcor/ac/cmnd",
                    "apply": "state.global.HVAC = state.global.HVAC || {}; state.global.HVAC.Temp = message; return (JSON.stringify(state.global.HVAC));"
                },
                "getCoolingThresholdTemperature": "amcor/ac/stat/temp",
                "setHeatingThresholdTemperature": {
                    "topic": "amcor/ac/cmnd",
                    "apply": "state.global.HVAC = state.global.HVAC || {}; state.global.HVAC.Temp = message; return (JSON.stringify(state.global.HVAC));"
                },
                "getHeatingThresholdTemperature": "amcor/ac/stat/temp",
                "setRotationSpeed": {
                    "topic": "amcor/ac/cmnd",
                    "apply": "state.global.HVAC = state.global.HVAC || {}; state.global.HVAC.FanSpeed = 1; return (JSON.stringify(state.global.HVAC));"
                }
},

Any help and guidance will be very much appreciated.

Thanks,

LDellus

I am confused. Why are you asking this question here? Seems more a homebridge question.

I'm guessing that you're using IRMQTTServer, have you looked at:

IRremoteESP8266/examples/IRMQTTServer/IRMQTTServer.h

Lines 135 to 136 in 0f94857

    
           // Enable sending/receiving climate via JSON. `true` cost ~5k of program space. 
        
           #define MQTT_CLIMATE_JSON false

Which should allow you send multiple settings in a single MQTT (JSON) message.
or change this:

IRremoteESP8266/examples/IRMQTTServer/IRMQTTServer.h

Lines 138 to 152 in 0f94857

    
           // Use Home Assistant-style operation modes. 
        
           // TL;DR: Power and Mode are linked together. One changes the other. 
        
           // i.e. 
        
           //  - When power is set to "off", the mode is set to "off". 
        
           //  - When the mode changes from "off" to something else, power is set to "on". 
        
           // See: https://www.home-assistant.io/components/climate.mqtt/#modes 
        
           // *** WARNING *** 
        
           // This setting will cause IRMQTTServer to forget what the previous operation 
        
           // mode was. e.g. a power "on" -> "off" -> "on" will cause it to use the 
        
           // default mode for your A/C, not the previous mode. 
        
           // Typically this is "Auto" or "Cool" mode. 
        
           // Change to false, if your home automation system doesn't like this, or if 
        
           // you want IRMQTTServer to be the authoritative source for controling your 
        
           // A/C. 
        
           #define MQTT_CLIMATE_HA_MODE true

So that Power & Mode are not linked. i.e. you can leave Mode as Auto and just change Power between on & off.

Hi David,

Thanks for the guidance. I do use IRMQTTServer, but didn't pay attention to these settings. I will have a look and see if they help.

I thought that since I use IRMQTTServer, my question belongs here.

Do you plan to support Homekit natively at some point?

Thanks,

Laurent

Yes, we do support IRMQTTServer. It wasn't clear you were using it. I.e. you didn't mention it.

Re: Homekit. I have no immediate plans. Feel free to add it.

Hi David, Thanks a lot for your assistance. The second setting solved my problem, but with a twist. Indeed decoupling the power and mode allows me to turn on the AC because it remembers the last mode. The problem though is that I have first to use the webui to set the protocol and the mode, otherwise it doesn’t work. I will try the first option, as it should allow me to always specify the protocol and the mode. I’ll let you know if it works.

You should only need to set the protocol once, as IRMQTTServer will store the settings (via RETAIN) on your MQTT Server.
Mode should similarly be saved as well.

David, how can I hard code the protocol and model in IRMQTTServer.h?

You shouldn't need to, but you would need to add/change code here:

IRremoteESP8266/examples/IRMQTTServer/IRMQTTServer.ino

Lines 3078 to 3080 in 2bad027

    
           const stdAc::state_t next = ac->getState(); 
        
           const stdAc::state_t prev = ac->getStatePrev(); 
        
           if (prev.protocol != next.protocol || forceMQTT) {

e.g. The following should hard code it for you.

  stdAc::state_t next = ac->getState();  // Changed
  const stdAc::state_t prev = ac->getStatePrev();  // Unchanged
  next.protocol = decode_type_t::NAMEOFAIRCON;  // Added. You will need to change this.
  next.model = 2;  // Added. You will need to change this to what ever model number you need.
  if (prev.protocol != next.protocol || forceMQTT) {  // Unchanged

or change the default here:

IRremoteESP8266/src/IRsend.h

Lines 98 to 99 in 2bad027

    
           decode_type_t protocol = decode_type_t::UNKNOWN; 
        
           int16_t model = -1;  // `-1` means unused.

But seriously, you are probably doing something wrong. You should only need to set it once, and MQTT will remember it for you.

I haven't tried the code changes above. But it should give you the jist of what you need to do.

Thanks David. I need to investigate further why after a power outage it loses its settings. The easy fix is to hard code the protocol and model but I totally agree that I shouldn't have to do that.
